SPECIFICATION forming part of Letters Patent No. 725,287, datedlAprl 14, 1903. Application filed August 21,1902. Serial No. 120,550. (No model.)

To all 1,071,011?, tmc/,y concern:

Be it known that we,ALFRED RoBERTs,fore man, residing at S3 I-Iollydale road, Peckham, S. E. in the county of London, FRANK YOUNG, fruit-merchant, residing at Monument Buildings, Pudding Lane, East-cheap, E. O., in the city of London, and JANE CAROLINE SMITH, spinster, residing at 47 Jevington Gardens, Eastbourne, in the county'of Sussex, England, 1o all subjects of the King of Great Britain and Ireland, have invented certain new and useful Improvements in Window-Cleaners, of which the following is a specification.

This invention relates to an improved device for cleaning windows, and comprises means for gripping the cloth or other similar article used for this purpose and securing it to the end of a rod. For this purpose the end of the rod is fitted With a metal tube, to which 2o is pivoted a bent or cranked brass or other metal rod or wire, the outer ends of which are cranked for supporting a metal plate pivoted' thereto. The cloth is folded over the said plate, and its ends are gripped tightly to secure it thereto by means of two jaws or grippers formed, preferably, of stout galvanized wire which is waved or corrugated longitudinally to form projections and recesses for gripping the cloth when using the same. The 3o upper jaw is supported at each end by wire frames or carriers fixed to the aforesaid tube above the pivoted rod or wire. The lower jaw is supported at each end by side rods or wires pivoted to the tube below the said rod or Wire carrying the plate, and these side rods or wires carry a support or pawl, which when they are raised for gripping the cloth engages with a toothed plate or rack fixed lto the tube for holding the said jaw in its locked posi- 4o tion. The cloth iseasily removed by disen gaging the pawl or support from the rack and lowering the lower jaw.

In the accompanying drawings, Figure l is a side elevation of the device in its unlocked position. Fig. 2 is asimilarview in its locked 45 or gripping position, and Fig. 3 an elevation at right angles to Fig. l.

rl is the rod, and b the tube, fixed thereto by the pin c, carried by the chain c.

d is the cranked rod or wire, and c is the 5o plate pivoted to the ends of the same by means of the sockets or plates e'.

fis the upper jaw, and g the frames or carriers supporting the same and iiXed to the upper end of the tube h.

7L is the lower or movable jaw carried by the rods or wires t, pivoted at i" to the tube b, and'kis the support or pawl fixed to the said wires.

Z is the toothed plate or rack fixed to the 6o tube b and with which the pawl k engages when the lower jaw is raised to its gripping position.

When using the device,` the cloth for cleaning the window is folded around the plate e, 65 and its two ends are placed between the jaws fand h. The lower jaw 71 is then raised so as to grip the cloth between it and the upper jaw g, the pawl or support 7c engaging with the rack l, and thus keeping the jaw 7L in its 7o raised position, as shown in Fig. 2, and causing it to tightly grip and hold the cloth to the plate e. The operator then works or rubs the cloth over the surface ofthe Window by means of a rod or handle a', the pivoted plate c per- 75 initting of the requisite movement of the latter.

Having now fully described the nature of our said invention, what We claim, and desire to secure by Letters Patent, is-

l. The improved device for cleaning windows comprising a tube tixed to the top of a rod, a plate carrying the cleaning-cloth, pivoted to the ends of a cranked rod or wire In witness whereof We have hereunto set our hands in the presence of Witnesses.
